The technical standard parameters of domestic first-class medium-density fiberboard are as follows:
(1) The thickness deviation of the plate should be small, and it should generally be controlled at ±0.3mm;
(2) The expansion rate of water absorption thickness ≤12%;
(3) The free formaldehyde content does not exceed 70mg/100g;
(4) Screw holding force: 1150N ≥ vertical plate, 660N ≥ parallel plate; (5) The static bending strength of the plate ≥17.2MPa;
